# Display the power consumption of the day – Arduino power meter

> Display the power consumption of the day – Arduino power meter

Original author: arms22 (source: http://arms22.blog91.fc2.com/?no=517)

## Components

- **Arduino Ethernet Shield** x 1 ([docs](https://docs.arduino.cc/retired/shields/arduino-ethernet-shield-without-poe-module))

## Article

This project is a power consumption monitoring application using ethernet shield and XivelyPachube ※ 2 to the upload + accumulate the data in anywhere and at any time.

Using the accumulated data “Today’s power consumption” or “highest and lowest power of today” are displayed.

– Prototype

It makes a part that measures the voltage and current required for the power calculations.

– 100V Transformer

The power transformer of 100V side of the wire, parallel connect the varistor in, put a fuse in series.

– Using Ethernet shield

Data measured by the Arduino power meter to Pachube (patch bay).

Pachube’s a web service that can be shared, such as environmental data and sensor data via the Internet.
